Hi all,
I just replaced my LCD and when I boot up my phone the display seems to work but after 1 or 2 seconds the backlight shuts off. The screen is fully functional; touch works as well as the pixels. I can only see the pixels by holding the screen at a 45 degree angle while shining a flashlight.
Any solutions? Did I connect anything wrong?
Esta é uma boa pergunta?

I've had a very similar symptom happen on an iPad 2 for example.
I fixed it by cleaning the screen connector on the board with a soft bristle brush and 99% isopropyl alcohol, wasn't making a full connection so backlight would shut off because it couldn't get full power.

That doesn't seem to work. Also I forgot to mention that the backlight of the broken screen is working when I try that one.

Found out that one pin was stuck in the motherboard connector. It was not making contact with display connector.
Check the pins under the microscope.

Hey, have you found the solution. I have the same problem. It works just with original display and no other.
